GenEvo (Gene Regulation in Evolution: From Molecular to Extended Phenotypes ) is a DFG funded Research Training Group organised in a collaboration between the faculty of biology of Johannes Gutenberg University Mainz (JGU) and the Institute of Molecular Biology (IMB). The initiative is centred around the core question of how complex and multi-layered gene regulatory systems have evolved.

Happy start into the new year: the manuscript of E. M. Griebeler and N. Klein on the Topic "Life-history strategies indicate live-bearing in Nothosaurus (Sauropterygia)" was accepted in the Palaeontology Journal.
In another international collaboration published in BMC Microbiology we show that antibiotic and gamma-radiation treatment disturbs the endosymbiont community in tsetse flies which changes the composition of pheromones on their body surface and impacts mate choice.
